本研究旨在探讨猪腰大肌肌节长度的变异。制备显微镜载玻片，并在Nomarski对比度下评价肌肉-进行了150次测量。随后，肌节长度的三个不同的，有代表性的肌原纤维进行了测量每种肉。肌原纤维肌节长度值呈正态分布。猪肉的肌节平均长度为3.28 ± 0.23 µm，野猪肉为2.51 ± 0.14 µm-动物之间的差异具有统计学显著性（p = 0.0000）。指出猪肉肌节长度取决于肌原纤维。野猪肉的肌节长度与猪肉相比变化较小。这种差异反映在更强硬的野猪肉质地。
The aim of the research was to evaluate the sarcomere length variation in Psoas major muscle in pork and wild boar tenderloin. Microscopic slides were prepared and muscles were evaluated in Nomarski contrast – there were made measurements with the number of 150. Subsequently, sarcomeres length of three different, representative myofibrils were measured for each kind of meat. Values of sarcomere’s lengths of myofibrils were characterized by a normal distribution. The mean length of sarcomere was 3.28 ± 0.23 µm for pork meat and 2.51 ± 0.14 µm for wild boar meat – difference between animals was statistically significant (p = 0.0000). It was stated that sarcomere length for pork meat was dependent on the myofibril. A lower variation in the sarco mere’s length of wild boar meat in comparison with pork meat has been shown. This difference is reflected in tougher wild boar meat texture.
